Introduction

The dilemma of 'annual crop rotation' in Bupleurum chinense cultivation in Yongnian District, Hebei Province, has been resolved through the live microbial technological application of Green Nitrogen Biotech.

Traditional Chinese medicinal materials have stringent soil requirements. In Yongnian District, Hebei Province, the annual rotation of Bupleurum (Chaihu) cultivation necessitates soil improvement through live microbial application, which effectively prevents soil compaction and eliminates the risk of pesticide residues. This approach not only achieves environmental sustainability but also significantly enhances economic returns. The application of live microbes has demonstrated critical efficacy in transitioning Chinese herbal medicine cultivation to an ecological and sustainable model, providing innovative solutions for distributors of herbal medicine inputs.

Data from the Hebei Yongnian District Agricultural Technology Extension Center, which participated in the '2025 Hundred Counties, Ten Thousand Acres Soil Health and Yield Enhancement Demonstration Initiative,' revealed that the total income per hectare increased by over 3,000 dollars in the Bupleurum chinense (Chinese Bupleurum) cultivation demonstration area of a family farm in Jiangwu Town after applying live microbes.

"Chinese Bupleurum requires annual rotation. After applying live microbes this time, the soil became looser, reduced the use of fertilizers and pesticides, and the root system of the plants grew much stronger than in previous years," said the agricultural technician from Yongnian District.

The plants with activated microbial root-injected Bupleurum chinense had robust stems and deep green color.

Controlling Fertilizer and Reducing Chemicals: Practicing Green Cultivation of Chinese Medicinal Materials

According to the feedback from Yongnian District Agricultural Technology Extension Center regarding the yield increase: the target crop of the demonstration area, Bupleurum, utilized biocontrol live microbes by Green Nitrogen Biotech fermentation equipment, with three full-course applications.

Compared with the control group, the soil treated with live microbes exhibited improved looseness, enhanced aggregate structure, and a higher proportion of beneficial bacteria. This activated the soil, released nutrients, and created a favorable ecological environment for the root system of Bupleurum, promoting root thickening and growth while reducing chemical fertilizer usage by 20%. Simultaneously, it inhibited the proliferation of harmful pathogens, effectively suppressing soil-borne diseases. The population density of pests such as aphids and thrips was directly reduced by 86.2%, and the use of chemical pesticides decreased by 25%, ensuring healthy growth of Bupleurum.

The application of live microbes from Green Nitrogen Biotech not only reduces the chemical burden on soil and crops, but also meets the quality requirements for green cultivation of traditional Chinese medicinal materials.

Green Nitrogen Active Microbes: Strengthening the 'Health Defense Line' of Traditional Chinese Medicinal Materials

The China Pharmacopoeia sets strict limit standards for pesticide residues in traditional Chinese medicinal materials. According to the general requirements, 33 prohibited pesticides must not be detected in medicinal materials and decoction pieces (must not exceed the quantitative limit).

Under the agricultural trend of 'reducing input and enhancing efficiency,' green nitrogen biotech live microbes facilitate the transition of traditional Chinese medicine (TCM) cultivation towards 'light chemistry and heavy ecology,' fundamentally eliminating pesticide residue risks. The resulting TCM products are safer, better aligned with market demands, and exhibit enhanced competitiveness.
